Message from President
As global warming is becoming apparent, regeneration of the forest whichplays an important role in CO reduction is reconsidered. Based on thegovernment policy, diversified use of the forest is evolving day by day, as
seen in the stadium for Tokyo Olympic 2020.
We, Oshika Group, offers our advanced methods to utilize wood material
through our adhesives for wood by using the technology that we has
cultivated over the past 100 years. Not only promoting the coordination ofliving environment with coziness and warmth of wood, we will contribute toa sustainable, recycling society by spreading the wood utilization worldwide
and by promoting the cycling of forest regeneration, wood utilization andforest farming. Furthermore, we will contribute to developing processing
technologies for other various materials besides wood material throughOshika Corporation
adhesives.
Based on this philosophy, Oshika Group, as “ONE TEAM”, makes thechallenge and wholeheartedly responds to a request of customers, aiming
for a trusted company.

7．Core Product
Oshika‘s core product is adhesive for building
materials. Inheriting the technology since thefoundation, we have significant advantages
particularly in adhesives for plywood (phenol resinadhesive) and for laminated timber (Aqueous
polymer-isocyanate adhesive, resorcinol adhesive).
Besides that, we have a great number of sales
performance in the field of not only adhesive forconstruction and emulsion for building materials but
treatment chemicals for wood as well. For the past
few years, the adhesive sales performance in nonindustry field ( Vehicles and home appliances) also
shows its growth.

11．GIR Joint System

GIR（Glued-in Rod ）joint system

Beautiful appearance
by GIR joint system

GIR (Glued-in Rod) is a kind of joint systemusing rod and adhesive in timber structure.

GIR joint system is an innovative jointing technology
to conceal the metal joint part by placing steel rod
inside timber.
Oshika has developed a new epoxy resin adhesive tostrengthen its joint part by filling adhesives into thespace between rod and timber.

2. Long-term anti-loosing performance
3. No stress when jointed
4. Simultaneous anchoring on joint parts
5. No damage to the dimension of timber

12．Lignin Phenol

Lignin phenol resin

Oshika developed a new adhesive made from “Lignin(included in trees)” as one of the materials.
Lignin is generated as a by-product in the papermaking process, most of which had been used for fuel.
This resin is a polymer included in the plant cell wall. Even though lignin had been researched
in order to use it for the material of adhesive, however it was rarely used because of its weak reactivity
compared with phenol.
As being extracted not from oil but from wood, Oshikaʼs new Lignin phenol resin enabled us tosustainably produce adhesives.

13．Flame Retardant

Flame retardant
One of the disadvantages of timber as
construction material is “it burns”.
Oshika succeeded in creating a flame retardant
which performs well enough to acquire“incombustibility certification” set up by Ministerof Land, Infrastructure, Transport and Tourism.
Generally, flame retardants for timber often cause
efflorescence by absorbing moisture. However,Oshikaʼs flame retardant can reduceefflorescence appearing on the surface.
As it never causes disfigurement of the woodmaterial, timber which is treated flame retardants
can be applied to wherever it needs flameretardancy.

14．CLT

CLT(Cross Laminated Timber)

CLT(Cross Laminated Timber) is an enormous andthick wooden material, which each layer of thealigned saw board is laminated perpendicular tothe previous layer. It has been used forconstructional material as well as civil engineering
material and furniture.
Firstly developed in Austria around 1995, CLT has
been used for various buildings in Europe, mainly inBritain, Switzerland and Italy. Rapidly gaining
popularity in Canada, the United States andAustralia in recent years, CLT is used to build highrise buildings in those countries.
It is often adopted to house and mid-riseapartment as well as living space of nursing homeand guest room of hotel, using its characteristics ofinsulation and box frame. Not only as a frame ofconstruction, CLT potentially has the multiple
benefits of thermal insulation, flame shielding andsound insulation performance.
CLT also offers a cozy space with a warm wood
texture and grain. Besides, since wood is asustainable, recycling resource, it allows us to22/23
construct

14．CLTbuildings by using forest resources effectively
while reducing CO2 emissions.
There are other advantages as well. As CLT iscarried in construction field after somematerials are assembled infactory(prefabrication) and the joint part isvery simple, so it does not require a long
construction period and any expert skills. It is
possible to store and assemble as temporary
housing parts in a time of disaster.
Furthermore, CLT is much more lightcompared with RC(reinforced concrete)constructions.
Oshika is always ready to offer the suitableadhesive for CLT manufacturing.
